How to exclude today from all widgets / reports

By default Matomo shows logs up to today, but we are using a post-hoc web log analysis process (with zero cookies), which adds the logs to Matomo at 2am on a cron.

How can we configure Matomo to
(1) ensure that (by default) ‘today’ is not shown on reports or widgets, given that it’s always zero.
(2) similarly, set the period (Week/month) on Personal Email Reports to exclude ‘today’ as the final day of the report (which, because we are using a post hoc log process, is always empty!)
